Pros: Remembers to lower heat when you don't
Cons: Doesn't always remember to lower hear when you don't
This system is simple to install and seemingly simple to program. We often notice that it doesn't obey our commands, such as raising and lowering temps at set times. While this has proved to be frustrating, due to our lack of trust it has made us pay more attention to out thermostat and assure ourselves that we are not wasting fuel.
